SANDAL.

Serial No. 621,421.

. To all whom it may concern:

Be it known that I, DANIEL W. CHAsE, a citizen of the United States, residing at Bradford, Haverhill, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sandals; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to sandals.

The great objection to the ordinary bathor bed-room sandal is its tendency to drop from the foot of the wearer in walking which necessitates a scufling or shuflling gait on the part of the wearer to keep the sandal on the foot.

One object of the present invention is to produce a sandal which may be readily slipped on and off the foot but which at the same time will be snugly held on the foot of the wearer and will have no tendency to drop off in walking even though the wearer lifts his foot as in ordinary walking.

Another object of the invention is to produce an improved sole which, although it is particularly applicable to a sandal, may nev ertheless be used for a shoe or similar article.

Still another object of the invention is to so combine the straps or flaps which hold the sandal on the foot with the sole that thesandal may be assembled and manufactured very cheaply.

WVith the above objects in view, the present invention consists in the sandal hereinafter described and particularly pointed out in the claims.

In the drawings, Figure 1 is a view, in perspective, of the'sandal; and Fig. 2 is a cross section taken through the sole of the sandal just back of the flaps which constitute the upper of the sandal.

Referring to the drawings, the sandal comprises a sole 1, two straps or flaps 2 and 3 which are secured ateither side of the ball portion of the sole and are adapted to be brought up over the arch of the foot, and an elastic lacing 4 by which the free ends of the flaps 2 and 3 are laced together over the top of the foot. When the foot is put in the sandal, the lacing 4: yields and holds the flaps 2 and 3 snugly over the top of the foot. WVhen the foot is bent in walking, the lacing 4 yields somewhat to the arch of the foot making the sandal more comfortable to wear in walking, and when the foot is flat in the sandal the elastic lacing 4 causes the flaps 2 and 3 to hug the foot and effectually prevent the sandal from dropping ofl, so that the wearer may raise his feet in walking with no likelihood of the sandals dropping off." This advantage over the ordinary type of Chinese or Japanese sandals is obvious and contributes greatly to the comfort of thewearer especially in going up or down stairs. By using an elastic lacing it is possible to make the flaps 2 and 3 of ordinary cloth, thus cheapening the cost of manufacture and at the same time attaining all of the advantages of an elastic upper for the sandal and also making the sandal adjustable for feet of different thicknesses. Moreover since the lacing 4 is the only part of the sandal which contains rubber or like elastic, it may be thrown away and a new lacing substituted whenever the rubber loses its elastic qualities. i

In manufacturing the sandal, two pieces 5 and 6 of leather-board are cut in the shape of the outline of the foot. -These pieces of leather-board are then coated with an adhesive compound such as cement, and pieces of cloth 7 and 8 are pressed against the faces of the pieces of leather-board andthus ce- Specification of Letters Patent.

mented thereto. The free edges 9 of the board and laid flat against the opposite faces of the leather board. The piece of cloth 7,

which covers the piece of leather -board which forms the bottom of the completed sandal, is preferably of a piece of wear-resisting canvas, while the piece of cloth, which forms the upper surface next to the foot, is' preferably of some softer material. The two cloth covered pieces of leather-board are then laid together with their cloth covered faces exposed. The lower edges 10 and 11 of the flaps 2 and 3 are-placed between the edges'of the two pieces of leather-board and a lineofstitching 12 is sewn through both pieces of leather-board near their edges, thus firmly uniting the two pieces of leatherboard and the lower edges of the flaps 2 and 3 which lie-between them.

The stitching passes through the free edges of the cloth coverings 7 and 8, which edges of the cloth bind the edges of the leather-board and prevent these edges from breaking, and also provide tour thicknesses of cloth to support the line of stitching. ()n account of its weakness the leather-board could not of itself sustain the stitches and it is of advantage to have the stitches pass through as many thicknesses of binding material as possible. The use of the turnedover edges of the cloth coverings of the leather-board allows the sandal to be manufactured much more cheaply than if a separate strip of tape were sewn around to bind the edges of the sole. In thisv connection it is to be noted that but a single stitching operation is required in making the completed sandal, said stitching operation serving both to unite and bind the edges of the sole portion and also to assemble the upper portion or flaps therewith. After the flaps 2 and 3 have been sewn to the sole, they are turned up and their upper or free edges laced to gether by the elastic lacing 4 which passes through suitable eyelets 13 in the edges of the flaps. The flaps 2 and 3 consist of fabric which is preferably stiffened somewhat so that they will stand up from the sole to allow the foot to be readily slipped into the sandal. The sandal is very cheap to manu facture, presents an attractive appearance and may be packed in a very small space for shipping.

While the sole is preferably shown as embodied and constituting a part of the sandal, it will nevertheless be evident that the sole may be equally well used in the manufacture of light house shoes or slippers. It is evi dent that other material, such as pasteboard,

straw-board or leather, may be used in the place of leathenboard in making the sandal, L

and hence the term leather-board, as used in the specification and claims, is intended to define stiflening material possessing the qualities of leather-board.

While a preferred embodiment of the present invention has been illustrated and described, it is nevertheless to be understood that the invention may be embodied in other forms within the scope of the following claims.

1. A sole for a shoe, slipper or the like, having, in combination, two pieces of leatherboard cut in the shape of the outline of the foot and united near their edges by a line of stitching, and cloth coverings for the pieces of leather-board, the edges of the cloth being tucked between the opposing faces of the leather-board and held by said line of stitching.

2. A sandal, having, in combination, a sole portion comprising two pieces of leatherboard and cloth coverings for said pieces of leather-board, said pieces of leather-board being stitched together by a line of stitching near their edges with the free edges of the cloth coverings tucked between them, and an upper portion comprising two flaps secured between the edges of the leatherboard at the sides of the ball portion by said line of stitching and an elastic lacing for lacing together the flaps over the top of the foot.
